Ethanol steam reforming reactors

Recently, Comas et al.219 performed the thermodynamic analysis of the SRE reaction in the presence of CaO as a C02 sorbent. The equilibrium calculations indicate that the presence of CaO in the ethanol steam reforming reactor enhances the H2 yield while reducing the CO concentrations in the outlet of the reformer. Furthermore, the temperature range at which maximum H2 yield could be obtained also shifts from above 700 °C for the conventional steam reforming reaction without CaO to below 700 °C, typically around 500 °C in the presence of CaO. It appears that the presence of CaO along with ethanol reforming catalyst shift the WGS equilibrium in the forward direction and converts more CO into C02 that will be simultaneously removed by CaO by adsorption. 

Llorca et developed a micro-channel reactor where ethanol steam reforming is performed on one side of the plate while ethanol combustion is performed on the with 14 microchannels. The results revealed that Rh-based catalysts exhibited the highest catalytic activity, when compared to Co and Ni. The Rh-Ni-Ce catalyst was operated for 100 h without any noticeable degradation in activity and selectivity. Full conversion was achieved for the entire period and the Hg selectivity was 86%. The CO content in reformate remained constant ca. 8.2%.

Similarly to catalyst development, activities dealing with integrated reactors and complete systems for steam reforming in microreactors are dominated by systems applying methanol as fuel, ethanol steam reformers being the exception.
